Cationic poly(phenylene vinylene) derivative (PPV) as photoelectrochemical active species was modified on the electrode. Under light irradiation, PPV could be excited and generate efficient photocurrent. PPV also had the ability to bind with negatively charged membrane of pathogenic microorganisms, which hindered the electron transfer between electrode and electrolyte. As a result, the photocurrent would decrease obviously. For <jats:italic>E. coli<\/jats:italic>, <jats:italic>B. subtilis<\/jats:italic> and <jats:italic>C. albicans<\/jats:italic>, the photocurrent density was reduced by 18, 33 and 59\u2009%, respectively.
